S2 Avant boost problems

[M_GORDON]

The Vagcom is "clear"
The boost leak test that we made was perfect.
Oil...yes, at the last oil change my mecha put on a 10w40 standar oil and the engine or the turbo eat it and with too powerfull uses pressure gones down and the tipicall sound off Cla-cla-cla will appears some times.

Now with mobil1 5w50 don´t appear this problem.

te dice que cambies el aceite y los taques

The Oil is a 5w50 Mobil1 with I don know how much kms
And the other pieces (taqués) are "new", the have around of 20k kms.
The car sounds "always" and because that I say to change them.

mobil 1 goes very thin, very quickly...this will not help your problem at all......my pressure dropped to 1 bar!!!....

[M_GORDON]

Ok thank U very much.

The next oil change will be with 10w50. I see one Castrol on ebay a little bit cheap

I think that your boost problem is not conected with oil pressure. my oil presure can drop to 1 bar , on idle and hot engine. this is normal..
change oil every 7000km, and use original audi oil filter...
10-50 or 10-60 are oil for our engines..

did you check your DV ? are they good?
do you have boost gauge or you look boost pressure on dash?

did you in mine time put some big intercooler on your car?
